Shortly after you get the RLS-7, you will cross a footbridge. This bridge overlooks a highway bridge where some enemy soldiers are fighting giant mutant spiders. Use the TDM on the other side of the footbridge to revert the lockers in the room. You can find a note inside one of them that reads: "My neighbor, he is pain in my assholes. I get a bear made of fur, he must get a bear made of fur. I get a can of meat, he must get a can of meat. I get an E99 technologies... he cannot afford. Great success!"Lost reference
Upgrade the TMD to its final level, then immediately break the vent behind the upgrade machine. Follow the crawlspace to find the underground wheel from Lost.
